Discovering Your Roots

Greetings, <Race>. I'm afraid I have little to offer here until my reagents are stocked. Of the supplies I require, there is a special reagent, razorthorn root, that is particularly difficult to harvest. Fortunately, I know a secret.... Using the glands of the Razorthorn flayers, one can control a ravager there and use it to expose a root. To find the roots, travel to Outlands and fly northeast from Shattrath until you reach Razorthorn Rise.
